Mesoscopically structured functional composite nonwovens for application in separation and catalysis (B08)

• Subject Area: Preparatory and Physical Chemistry of Polymers ; Polymer Materials
• Term: from 2009 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 79971943

The aim of the project is the fabrication of mesoscopically structured functional composite nonwovens consisting of electrospun polymer fibers and supramolecular fibers. These composite nonwovens are to be investigated in filtration and catalysis. For this purpose, functional polymers and tailored supramolecular building blocks have to be synthesized specifically with respect to their application. Two new concepts will be followed for the preparation of the composite nonwovens. This includes the systematic investigation of the recently discovered grafting of self-assembled fibers on electrospun fibers, as well as composite fabrication by wet-laid processes of electrospun and self-assembled fibers with defined fiber lengths. These composite nonwovens will be used for air filtration and for liquid filtration of metal ions. The nonwovens with immobilized metal ions and metal nanoparticles will also be used in organic catalysis.
